Application led November 19, 1918.

To all whom 'it may concern.'

Be it known that 1, KUWAKICHI FUJITA, a subject of the Emperor of Japan, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, have invented new and useful Improvements in Burglar- Alarms, of which the following is a speci-A ication. y

This invention relates to burglar alarms and*v the present invention is an improvement upon that filed ointly by Gertrude N. Markle and me on April 241, 1918, Serial No. 230,539..

The object of the present invent-ion is to provide improved means for actuating the device and for improving certain details of construction.

lVith the above and other objects in view the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

In the drawings:

Figure 1 is a rear view of the inventionA with the back part of the case removed,

Fig. 2 is a section on lthe line 2-2 of Fig. 1,

Fig. 3 is a section on the line 3--3 of Fig. 1,

Fig. 41 is a view of the actuating means,

Fig. 5 is a side View, partly in section, of the trigger releasing means,

Fig. 6 is a sectional detail showing the trigger and barrel, and

Fig. 7 is a view of the case which contains the parts.

As before stated the present invention is an improvement over that contained in the application now on file in the Patent @ffice In the said application a device is shown consisting of a central actuating device and a casing located in each room and containing a rotatable block having a number of barrels therein adapted tocontain cartridges and a housing connected with the block and.

containing triggers, with means actuating from' the central actuating device for rotating the block and releasing the trigger. In the drawings 1 indicates the casing, one of which` is located in each room. 2 indicates the block rotatably mounted in the casing and containing a number of barrels 3. 4: is the housing secured to one side of the block and containing the triggers 5. These triggers are actuated by the springs 6 and Specification of Letters Patent.

secured to one side of the casing and carry- Serial No. 263,191.

4each trigger has connected therewith a rod 7 extending transversely across the block and projecting through a slot 8 yin the casing. 9 indicates an actuating rod slidably ing bent arms 10 for engaging the ends of the rods 7. The upwardly extending ends of these arms are of different lengths, the shortest one being at the top of the rod a-nd the longest one at the bottom so that when the rod 9 is lowered the cartridges will be fired successively beginning a-t the top. The lower end of the rod 9 is bent at right angles 'to provide a hook 11. The other side of the casing slidingly carries a releasing rod 12,

retest-ea July 5,1921:

the upper end of which is adapted to en-4 gage with a. hole 13 in the top of the casing to hold the block against turning movement, which movement is given the block'by means ofthe spring 14-engaging the cable 15 secured to thedrum 16. This arrangement is shown in the other application. The-lower end of the rod 12 is provided with a hook 17.

The means for actuating the rods 9 and 12 consists of a roller 18 carried by a shaft 19 journaled in the lower part of the case.

A toothed disk 20 is secured to said shaft and a spring dog 21 carried by thefbottom ofthe case engages with the teeth as shown. y

its other end connected with the spool 22.

This ribbon passesaround al part of the roller 18. cured to the spool 27 and to a part of the roller v18. These ribbons are woundaround the spools 27 and 28 in opposite directions so that when the spool 22' is rotated by a key the ribbon 29 will unwind' from the spool 28 so as to rotate the shaft 24 and thus wind the ribbon 30 upon the spool 27 and unwind it from the roller 18 and thus rotate said roller, the dog 21 slipping over f the teeth andfthus permitting-this action.

31 indicates a shaft journaled in the casing and carrying a pair of spools 32 and 33. 341 indicates a ribbon wound upon one part of the spool 32.v The other end of said ribbon is wound upon a spool 35 secured to 30 indicates another ribbon se'- I the shaft 19 and so connected with said spool 35 that when the ribbon 30 is being unwound from thev roller 18 said ribbon 34 will be Vwound upon the spool 35 and willbe unwinding from the spool 32. A cablef is wound upon Athe other part of `the spool .32

Vman opposite-:direction from theribbon` 34 f and this cable is connected to a coiled .spring 37 having its -upper end connected with the case.V The spool 33 has wound thereon a cable 38 which 'carries a hook 39 at its free v end which is adapted to engager a part 40 on a releasing bar 41 which. is'provided with a -hook 42 at its upper end andhas itslower end sliding in a guide 'i-This guide 43Inay contain a spring for normally holdingV the bar 41 inlits raised position." 1

It will thus be seen that when the `spool j' `22 4is woundy up by ya key the ribbonswill act toiwindup the cable '36 on the spool 32 and thus Istore Aupenergy'in the spring 37. The. spring is held in extended positionby the j dogi 21 engaging the teeth of Vthe disk 20.

When the device is to be actuated a button,v is lpressed at the central station which closes anl electric circuit'46 which includes magnets 47. 15in-armaturev 48 is secured to Vthe dog 21 so that'when .the magnets are energized' the dog willbemoved out of contact.v with the teeth on lthe disk so as to per- 'mit'the spring 37 to revolve 4the spools and rollers and thus wind upvthe cable 38- This action will lower the bar 41 and as Vthe hook Y. 42 thereof isv iny engagement with 4 thel rod 12 said rodf 12 fwill be disengaged from the opening. 13 yand the springs 1'4y will rotate theblockr a 'half turn so Vas toicause the Fromdthe oregoingdescription taken in` connection with the accompanying drawings the simplicity .and advantagesY ofv the improvement will, it is thought, beperfectly' apparent to those skilled in the artto which such invention appertains without .f further detailed 4 description.

I desire it to be understoodvthat I may make changes in the construction and inthe combination and arrangement of the several parts, provided such changes allwithin; v vthescope of the appended claims.
